SPECIFICATION forming part of Letters Patent No. 774,262, dated November 8, 1904.

Original application filed ua y 6, 1902, Serial No. 92,839. Divided and this application filed July 26, 1902. Serial No. 117,065.

(No model-l To all whom, it may concern:

Beit known that we. HENRY W. MERRITT, a resident of Springfield, county of Hampden, and State of Massachusetts, and WALTER J. 5 BARRON, a resident of the borough of Brooklyn. county of Kings, city and State of New York, citizens of the United States, have invented certain new and useful Improvements in Type-l/Vriting Machines, of which the following is a specification. v

Our invention relates to type-writing machines, and more particularly to the carriagestop mechanism thereof; and the object of the invention is to provide simple and efficient mechanism of the characterspecified.

To these and other ends. which will hereinafter appear, our invention consists in the novel features of construction, arrangements of parts, and combinations of elements to be hereinafter described. and particularly pointed out in the appended claims.

In the accompanying drawings, wherein like reference characters designate like parts in the various views, Figure 1 is a plan view of the machine with certain parts broken away and others omitted. Fig. 2 is a side view, partly in section, of the upper portion of the machine. Fig. 3 is a detail rear elevation, partly in section, of aportion of the 3 machine, illustrating the margin-stops. Fig. A is an end View, partly in section, of the parts shown in Fig. 3 and looking in the direction of the arrow thereat. Fig. is a detail perspective View of the stop carried by the carriage. Fig. 6 is a detail perspective View of the stop carried by the frame of the machine. Fig. 7 is a detail perspective view of the deflecting piece or cam.

While we have shown our invention em- 4 bodied in a Densmore type-writing machine, it should be understood that the same maybe used in other forms of writing-machines and that accordingly various changes may be made without departing from the spirit of our invention.

The main frame 1 of the machine is provided with the usual top plate 2, which constitutes a portion of said frame. The top plate has upwardly-extending lugs or standards 3, that support a traverse-rail 4, which is surrounded by a sleeve 5, antifriction-balls 6 being interposed between said sleeve and g the grooved tracks 7 in the traverse-rail. The sleeve 5 is connected to a carriage-truck 8, that is guided by the rollers 9 on a fixed guide-rail 10, and the carriage proper, 11, is operatively connected to move with the truck by forks 12, whereas the front carriage-rail 0r cross-bar 13 is supported upon antifriction-rollers 14, carried by the shift-rail 15.

The top plate 2 is provided with a short rack 16, which is secured to the top plate by suitable bolts 17 and nuts 18. The front face of the rack 16 may be provided with a scale that corresponds to the scale on the papercarriage, as indicated in dotted lines in Fig. 8, except that the order or arrangement of the numerals is reversed that is to say, the scale on the carriage reads from left to right, while that on the rack-bar 16 reads from right to left. To the rear of this rack 16 is arranged a rod 19, which is secured at its inner end by a screw within a socket in the top plate 2 and is supported at its outer end in a hole in the rearwardly-extending ear 20 of the righthand standard or projection 3. Mounted upon this fixed bar or rod 19 is a U-shaped sheet-metal stop-frame 21, which has a cylindrical bearing that surrounds the bar 19, so that the frame is adapted to turn on the bar and be adjusted longitudinally thereon. This frame 21 contains between the side plates thereof a coiled spring 22, which bears at one end, 23, against a pin or rivet 24;, and the opposite end, 25, of this spring bears against the 8 5 rear straight edge of the top plate 2 of the machine, and the tendency of said spring is to force the frame forwardly and downwardly around the bar 19 and cause a tooth 26 upon the forward edge of the frame to engage be- 9 tween the teeth of the rack-bar 16, so as to hold said stop-frame in its adjusted position. The screw pin or pivot 24:, hereinbefore referred to, passes through a hole in the rear end of a margin-stop 27 and screws into a threaded hole in the frame 21. This marginstop is limited in its upward movement by a pin 28, which is secured to the stop and abuts against the top or horizontal portion of the frame 21. A spring 29 bears upon the pin 28, and thus normally maintains the pivoted margin-stop 27 in the elevated position. (Indicated in Fig. 4. It will be understood thatin order to adjust this margin-stop on the frame of the machine it is merely necessary to swing the frame 21 against the tension of its spring 22, and thereby release the tooth 26 from engagement with the teeth 30 on the rack 16. The frame 21 may then be moved longitudinally upon the rod 19 until the stop reaches the desired position as indicated by the scale on the front side thereof. If the frame then be released, the tension of the spring 22 will force the tooth 26 into locking engagement with adjacent teeth on the rack 16.

Cooperating with the margin-stop on the frame of the machine is a second margin-stop, which is carried by the carriage or its truck 8. Thus the truck is provided with a short rack 31, which is secured at one end by a screw 32 and at its opposite end by a screw 53, and this rack is likewise provided with a scale that corresponds to a portion of the front platen-carriage scale and reads in the same direction as the latter scale, as indicated in dotted lines in Fig. i). A margin-stop support or frame 34 is mounted and adapted to slide upon the rack 31. This frame 34 has pivoted thereto at 35 a pawl 36, the nose of which is adapted to engage with the teeth of the rack 31, the pawl being normally maintained in this engagement by a spring 37, which bears at one end against the tail of the pawl and at its opposite end against the frame 34 of the margin-stop, while a stud 38 on the pawl maintains the spring against lateral displacement. The frame 34 is provided with depending ears 39, between which is pivoted a stop 40, the pivot of said stop being indicated at 41, and the arrangement of this stop is such that it is normally maintained in the position represented. in Fig. 3 by its own weight. The stop 40 is provided at its upper edge with a Hat portion 42, which is adapted to abut against a corresponding portion on the frame 34 to limit the swinging movement of the stop in one direction. The stop, however, is free to vibrate around its pivot in the direction of the arrow thereon in Figs. 3 and 5, and the lower face of the stop is notched, so as to form a shoulder or abutment 43 to cooperate with the margin-stop 27 when the carriage is moved to the.

right. The frame 34 of the carriage marginstop is provided with laterally-projecting ears 44, which constitute bearings for one end of a carriage-release rod 45. This end of the carriage-release rod is flattened upon two sides, as indicated in Fig. 4, and projects through circular perforations 46 in the projecting ears arms by l l l 1 44. A cam or deflecting piece 47 has a stem which extends between the ears 44 and is hung upon the release-rod 45, so as to turn therewith. The said cam 47 is of segmental shape or has rounded ends and normally hangs vertically. The said cam is arranged back of and adjacent to the shouldered stop 40 with one end slightly in advance of the shoulder 43 and is adapted to depress the stop or arm 27, with which said shouldered stop normally engages, (when the carriage is returned to the right,) so as to permit the said stop to pass beyond the arm 27 and enable the operator to write within the margin. Ordinarily, however, said cam-piece alines with and passes through a notch 48 in the arm 27 and has no depressing effect thereon; but when the rock-shaft is turned by depressing the key or lever 49 in the direction of the arrow 51 in Fig. 2 the cam 47 is swung rearwardly in the direction of the arrow 2 in said figure and, acting upon the upper edge of the stop 27, presses it down slightly and enough to enable the shouldered stop 40 to pass over the stop-arm, thus permitting the carriage to be moved farther to the right than it could be moved but for the action of the cam. On the forward movement of the carriage the cam, which has previously been released by removing the linger from the key 49, will pass through the notch 48 in the stop-arm 27, and the stop 40 will swing freely around its pivot when it is brought into contact with the stop 27, and the carriage may therefore be fed from right to left without interruption by the right-hand margin-stop mechanism. The well-understood purpose of this arrangement is to permit the carriage to move to the right beyond the position where it is ordinarily stopped by the margin-stops, so that, if desired, writing may be done within the margin. During the ordinary operation of the machine the carriage will be moved to the right without depressing the release-key 49, and the marginstops will then be in position to arrest the carriage at the proper predetermined point. Owing to the fact that the margin-stop on the carriage and that on the frame of the machine are both adjustable, it is possible to obtain a greater number of stopping-points for the carriage, and hence a wider margin than could be obtained if only one of these stops were adjustable. For example, if there be twenty notches in the rack 31 on the carriage and twenty notches in the rack 16 on the frame it is possible to obtain a margin on the paper of a width equal to forty letter-spaces. Less than forty may be obtained by adjusting the stops on the carriage-rack.

It has been pointed out that the key or lever 49 and rock-shaft 45 constitute portions of the carriage-releasing means. Thus the rock-shaft 45 has rearwardlyextending arms 51 secured thereto, and secured to these screws 52 is a carriage-feed rack 53,

which meshes with a feed-pinion 54:, that is l operative connections between one of said intermittently rotated at eaclrdepression of any of the finger-keys or the space-bar to afford a letter-space feed of the carriage in the usual manner. It will thus be understood that a depression of the lever 49 raises the feed-rack from engagement with the feedpinion and releases the carriage from the escapement mechanism. This same movement of the lever 49 permits the right-hand marginstops on the carriage to pass the cooperating stop on the frame of the machine, as previously explained.

Certain of the features herein shown and described constitute no part of our present invention, but are claimed in a separate application, Serial No. 92,839, filed by us on the 6th day of February, 1902, and of which the present application is a division.
